I am also in Australia - and I know what you mean
The thing you need to thimk about is .... people do love cakes and yes, they will quite often remark that you should sell them
You should get into the habit of saying..... so - HOW MUCH would you be prepared to pay me to make this for you?
I can guarantee your illusion of doing cakes for a living will be shattered in ... probably the first 6 answers. It will probably shock you into reality :)
Its only in semi retirement that I have been able to do 'just cakes'
I have always been able to earn SO MUCH more from other careers than cakes
Fun to make - but by the time you pay registrations fees, insurances, re-modelling for council approval, equipment, classes (to hone your skills and improve) - you have a pretty hefty investment to recoup - especially hard these days when there is a cake decorater on every street corner, all pumped and rearing to do it cheaper than the next,
